Theodor (1810–1893) and Otto (1844–1906) Froebel belong to some of the most important Swiss garden designers of the 19th century and made a significant contribution to the emergence of Swiss landscape architecture in the 19th and 20th centuries
Their designs drew from their knowledge as gardeners. They ran a nursery with its own plant breeding program, which under Otto Froebel became one of the most important in Switzerland, gaining them international prestige, and brought their fascination for the biodiversity of the plant world as well as their design and breeding experience into their work.
Theodor and Otto Froebel continually expanded the inventory of their nursery with a number of new varieties of plants, both useful as well as decorative types. Their firm was known throughout Europe as an important station in the training of successive generations of garden designers and plant breeders, who worked well into the modern era of the 20th century.
